The labor saving wrench prevents overtightening by cooperating with a torque wrench

When the labor saving wrench prevents overtightening by cooperating with a torque wrench, make sure you have a reliable, standard labor saving wrench and torque wrench. The torque wrench should have accurate torque measurement and locking functions to ensure that the fastener can reach the predetermined tightening force without overtightening.
Understand the fastener requirements: Before starting work, carefully read the relevant technical information or consult professionals to understand the torque requirements of fasteners such as bolts and nuts that need to be tightened.
Check the tool status: Check whether the labor saving wrench and torque wrench are in good condition, including whether there are damaged, worn or loose parts. Make sure that the tool has been properly calibrated and maintained before use.
Set the torque wrench
Preset the torque value: Use the adjustment mechanism on the torque wrench to preset the appropriate torque value according to the requirements of the fastener. Usually, there will be a dial or digital display on the torque wrench to display and set the torque value. When presetting, be sure to ensure that the value is accurate.
Confirm the setting: After setting the torque value, you can confirm whether the setting is correct by gently turning the torque wrench. If you hear a "click" sound or feel the wrench suddenly stop turning, it means that the preset torque value has been reached.
Use with labor saving wrench
Connection tool: Connect the labor saving wrench to the torque wrench. Usually, the labor saving wrench will provide an interface that matches the torque wrench to connect the two. Make sure the connection is firm and reliable to avoid loosening or falling off during use.
Apply force: Use the labor saving wrench to apply force to the fastener. Because the labor saving wrench has the characteristics of torque multiplication, it can obtain a larger output torque with a smaller input force. In the process of applying force, maintain a smooth and uniform speed and force to avoid sudden increase in force and overtightening.
